2011-11-15ARM: pxa: add clk support in gpio driverHaojian Zhuang1-1/+25
Support clk in gpio driver. There's no gpio clock in PXA25x and PXA27x. So use dummy clk instead. And move the gpio edge initialization into gpio driver for arch-mmp. Signed-off-by: Haojian Zhuang <haojian.zhuang@marvell.com>
2011-11-15ARM: mmp: clear gpio edge detectHaojian Zhuang1-0/+4
Append code to clear gpio edge detect in gpio-pxa driver. Signed-off-by: Haojian Zhuang <haojian.zhuang@marvell.com>
2011-11-15ARM: pxa: change gpio to platform deviceHaojian Zhuang1-10/+125
Remove most gpio macros and change gpio driver to platform driver. Signed-off-by: Haojian Zhuang <haojian.zhuang@marvell.com>
2011-11-14ARM: pxa: use little endian read write in gpio driverHaojian Zhuang1-34/+34
Remove __raw_readl()/__raw_writel(). Use readl_relaxed()/writel_relaxed() instead. Signed-off-by: Haojian Zhuang <haojian.zhuang@marvell.com>
2011-11-14ARM: pxa: recognize gpio number and typeHaojian Zhuang1-1/+40
Use cpuid to recognize the gpio number and type. CPU_PXA26x is the special case since we can't identify it by cpuid. Signed-off-by: Haojian Zhuang <haojian.zhuang@marvell.com>
2011-11-14ARM: pxa: rename gpio_to_irq and irq_to_gpioHaojian Zhuang1-4/+85
Avoid to define gpio_to_irq() and irq_to_gpio() for potential name confliction since multiple architecture will be built together. Signed-off-by: Haojian Zhuang <haojian.zhuang@marvell.com>
2011-11-14ARM: pxa: use chained interrupt for GPIO0 and GPIO1Haojian Zhuang1-0/+14
GPIO0 and GPIO1 are linked to unique interrupt line in PXA series, others are linked to another interrupt line. All GPIO are linked to one interrupt line in MMP series. Since gpio driver is shared between PXA series and MMP series, define GPIO0 and GPIO1 as chained interrupt chip. So we can move out gpio code from irq.c to gpio-pxa.c.

2011-10-31Merge branch 'depends/rmk/gpio' into next/fixesArnd Bergmann1-0/+338
This sorts out merge conflicts with the arm/gpio branch that already got merged into mainline Linux. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2011-10-01ARM: 7104/1: plat-pxa: break out GPIO driver specificsLinus Walleij1-0/+2
The <mach/gpio.h> file is included from upper directories and deal with generic GPIO and gpiolib stuff. Break out the platform and driver specific defines and functions into its own header file.

2011-10-01ARM: 7103/1: plat-pxa: move PXA GPIO driver to GPIO subsystemLinus Walleij1-0/+336
As per example from the other ARM boards, push the PXA GPIO driver down to the GPIO subsystem so it can be consolidated. Acked-by: Eric Miao <eric.y.miao@gmail.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
